United States Patent 3,009,275 ADJUSTABLE FRAMES Herbert Olof Rosenberg,Vikstensvagen 41, Johanneshov, Stockholm, Sweden Filed June 27, 1960,Ser. No. 38,782 4 Claims. (Cl. 40-1521) This invention relates toadjustable frames or supports for pictures, placards, mirrors and thelike, and has for its object the provision of a device of the characterdescribed which is simple in construction and which is readilyadjustable to accommodate pictures, and so forth of varying size andconformations.

In the preferred form of invention, the frame is so constituted andconstructed that the same may be rolled or nested into relatively smallcompass.

Preferably, a frame of the invention comprises two strings or tapes ofiron which may be cut in desired lengths and which are fastened at thecorner of the pictures by means of hook-like members.

In the drawing:

FIG. 1 shows the rear side of a picture or placard provided with theframe according to the invention.

FIG. 2 shows a hook-like corner member composing one of the elements ofthe frame.

FIG. 3 is a side view of FIG. 2.

FIG. 4 shows a corner member fastened to a tape ele ment.

FIG. 5 shows a ring shaped member clamped on the tape member.

FIG. 6 is \a side view of FIG. 5.

FIG. 7 shows a modified corner member.

FIG. 8 is an end view of the modified corner member.

FIG. 9 is a sectional view on line 9-9 of FIG. 8.

FIG. 10 shows a metal plate to be folded in the form of a corner memberaccording to FIGS. 8 and 9.

Referring now to the drawing it will be seen that the inventioncontemplates a frame structure in which four corner plates 1 are coupledtogether pairwise by means of two-tape like flexible members 2. A wire 3is fastened to the tapes '2 in such a manner that the picture can behung on the wall. The corner plates engages the corner parts of apicture or placard 4 and the like by means of U-profiled flanges 5 and 6arranged in right angles to each other. The flanges 5 and 6 form the endportions of a back plate 7 engaging the rear side of the picture withits mat, glass and backing whereat the flanges are arranged to engage,receive, or accommodate an edge of the picture. An arcuate bow member 8concentric with the corner of the picture is produced by a stamping andpressing process so that the bow is spaced from the back plate 7 andforms a slit shaped opening 9 as shown in FIG. 3. The tape 2 is with itsend portion introduced into said slit shaped opening and is bent in sucha manner that the free end portion of the tape can be locked togetherwith the tape by means of a sleeve v10.

The only measure for the adjustment of the frame after the size of thepicture consists in cutting the two tapes 2 in suitable lengths.

"ice

The arcuate bow 8 concentric with the corner edge of the picture permitsdifferent directions of the tape 2 in dependence of the format of thepicture.

Each end of the wire 3 is fastened to a ring 111 consisting of two turns12 and 1 3 of a helical spring. The tape 2 is introduced between thesetwo turns of the ring 1 1 from above so that the ring serves as a hookcarrying the picture. Due to the tension of the spring the ring 11 ismaintained in position by the aid of the force of friction.

In FIGURES 7 to 10 a modified structure of the corner plate is shown.The corner plate is designated by 14 and differs from the plate 1 inthat the back plate 15 is double and consists of two layers 16 and 17and that the flanges 18 and 19 are connected to each other forming areal corner 20. The arcuate bow 21 is also doubled and produced in thesame manner as the arcuate bow 8. The double layers 16, v17 of the backplate impart to the con-truction increased tenacity and said layers arefastened together by means of the bow 21. The corner plates are producedof sheet material preferably of aluminium. The corner plate 14 consistsin developed form of two diametrically opposed sectors connected to eachother by means of the flanges 18 and 19 as shown in FIG. 10.

The sectors form the two layers 16 and 17 of the back plate. Afterfolding the stamped piece of sheet metal along lines 22 and 23 to formthe corner plate the arcuate bow 21 is formed by simultaneously pressingthe two layers '16 and 17. Thus, these layers will be locked together.

What I claim is:

1. An adjustable frame for a rectangular object comprising a pair oftape-like members including hook-like end portions, two pairs of cornerplates adapted to be fitted onto the corners of said rectangular object,each corner plate including an arcuate bow member arranged in a planeparallel with the object and concentric with the corner of the object,the hook-like end portions of the tape-like members engaging the arcuatebow members associated with a pair of diagonally situated corner plates.

2. An adjustable frame according to claim 1 in which each arcuate bowmember defines a slot shaped opening with the associated corner plate.

3. An adjustable trame according to claim 1 wherein each corner platecomprises a back including two layers connected with the associatedarcuate bow member.

4. An adjustable frame according to claim 1 in which the corner plate isof sheet material substantially in the form of two diametrically opposedsectors connected with each other.
